Serial No. 742,577.

To all 20720722, it may concern Be it known that l, Earns]? L. Fannow, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and tilt-ate of t hio, have invented certain new and useful improvements in Extensible Sup-- ports for Beil-ltilattresses, of which the following is a specification.

This invention appertains to an extensible support for bed mattresses, substantially as shown and described and particularly pointed out in the claims.

in the accompanying drawings, Figure 1 is a plan view of a mattress or mattress section embodying my invention. Fig. 2- is a cross section of aportion of the mattress in rest position on the slats of a wooden bed, and F 3 is a similar view but showing a n'ictal rail. Fig. 4 is a cross section of the complete mattress and the side bars or rails of a metallic bed frame, the relations herein being the more common one in iron-beds. Fig, is a perspective view of a portion of the bottom of the mattress frame, and Fig. 6 is a perspective view of a portion of one of the adjustable side extensions of said frame. Figs. 7 and 8 are perspective views of modifications of the invention.

As thus shown the invention resides es sentially in the side extensions of the mattress base by which the mattress is made adaptable to both metal and wooden beds of different widths. To this end the invention comprises a mat-tress in having a base with angle or iL-shaped bars 2 along its sides provided with occasional slots 3 lengthwise in its side flange or face and rod or bar 4i lengthwise in said base near its respective sides. The said base in all other respects may conform in size and style to the usual base of spring mattresses of this general character, and has transverse angle-iron bars 5 at intervals traversed by the said rods. The said slots and rods particularly belong to my improvement, and the rods are im movably fixed in the said base.

The extension itself comprises an angular or L-shaped bar 6 for each side of the mattress and a series of lateral projections, arms or members hereinafter referred to as stirrups 7 and rigidly fixed at one end to said bars and engaged through said slots upon the said rods l at the other end. The said stirrups are therefore somewhat peculiarly constructed to adapt them to this use as seen clearly in Fig. 3. Thus, the outer ends are shown as bent at right angles at two points to l.-shapc, thus forming, a relatively hi 'h shoulder a which comesopposite the outer depending side of the angle-bar (J and pro vides a substantially hook-shaped hanger adapted to engage upon the angular side rail Z) of the bed frame. in this construction the bar 6 constitutes the hook proper because it overlaps the outside of the said rail Z). The inner ends of the stirrups 7 are bent reversely and in ell'ect torm loops slidablc within limits on said rods, the extremities of the said stirrups being lapped back beneath the body thereof a suiiicient length to provide for the lateral widening or narrowing of the mattress support according to the width of the bed on which it is to be placed. It will be seen by this con struction of the said extensil'ile means that each side extension with its bar 6 and stirrups 7 is made a complete unitund adapted to be moved bodily inward or outward as may be required. In asscml'iling the said parts the extremities (Z of the said stirrups can first be projected through the slots 3 and then bent reversely to engage over the rods 4, and the weight of the mattress is sustained by the said stirrups in and through the said slotted bars 2. In the case of a wooden bed-stead or frame the base 2 will rest upon the wooden slats of the bed, and the said side extensions are adjusted accordingly to come within the side rails as shown in Fig. 2. In beds having angle-iron side rails which rest in reverse position to that shown in Fig. l, the bars 6 rest as illustrated in Fig. 3.

In one sense the stirrups 7 with the bars 6 constitute hangers for the mattress and the length of the shouldered portion a is such as to bring the mattress base to the proper level in respect to the sides of the bed.

Any preferred superstructure for the mattress base may be employed whether of the style herein shown or soi'nething materially different therefrom.

The modification, Fig. 7, shows a stirrup or hanger 7 with a twist in the shank which turns the. inner end edgewise vertically, and this end has a slot 10 lengthwise ostensibly engaged on the rod 4-. H

In Fig. 8 the stirrup 7 has a flat or hori zontally disposed inner end with a slot lengthwise and a flat bar 4 is used instead of a rod and a headed pin screw or the like through said bar and the said slot 12 slidably engages said parts together with the same effect as in Figs. 1 to 6. Obviously other equivalent modifications could be suggested.

hat I claim is:

1. A bed mat-tress having rods lengthwise in its base and extensions for said base consisting each of a single rigid bar and a series of stirrups fixed thereon and having slidable engagement on the said rods.

2. A mattress frame having rods lengthwise in its base next within the sides thereof, in combination with extensions comprising rail-engaging bars and a series of stirrups fixed thereon and having shoulders opposite the outer sides of said bars and inner ends looped over said rods.

3. A mattress having a base with side bars provided with slots at intervals and means adjacent thereto to slidably support side extensions, in combination with a series of side extensions having means to rigidly connect the same for joint movement and common support upon the rails of a bed.

4. A mattress having abase with lIOIl side bars provided with slots at intervals and rods lengthwise at its sides behind said bars, in combination with extensions at each side comprising a series of stirrups engaged through said slots on said rods and bars rigidly connecting the outer ends of said stirrups.

5. A bed mattress having supporting extensions at each side consisting of an L- shaped bar longitudinally disposed at the side of the mattress and supporting mem here at intervals fixed at their outer ends to the horizontal portion of said bars and longitudinally disposed rods in the frame of the mattress on which said members are engaged, whereby the mattress is adapted to bed frames of difierent widths.

In testimony whereof I affix my signature in presence of two witnesses.
